To Complete the Update of the Flash PROM
If power was interrupted during the flash PROM update procedure, it is possible
that one or more system boards were not updated successfully. You must become
superuser and complete the flash PROM update.
● At the # prompt, type the following:

Interruption
● Call your Sun service provider or local Sun service Authorized Service Provider.
▼
To Recover a Multi-Board System After Power
Interruption
Only one board is updated at any given time in the flash PROM updating process. If
there is a power interruption to the system while the flash PROMs are being
updated, only one board will have its flash PROMs in an inconsistent state.
Note –
Power interruption during updating of the flash PROMs aborts the updating
at the point of the power interruption. Turn the keyswitch to the Standby position
(
FIGURE 5-1
) to prevent power surge to the system when power is restored.
The following recovery procedure requires another board of the same type with an
uncorrupted PROM image (if you are updating an “I/O Type 1” board, you must
use another “I/O Type 1” board). In the following code examples, the flash PROM
on board 3 recovers by copying the flash PROM image from board 0.
1. Connect a null modem cable to port A and to either a terminal or a Sun™
Workstation™.
